Core services and the New Zealand health reforms.

The last 5 years have seen dramatic changes in health care provision in New Zealand. Amidst considerable controversy, the 14 Area Health Boards were abolished in July 1993. The State now funds 4 Regional Health Authorities (still on the basis of a weighted population formula) from Vote Health (the health sector's share of public expenditure). The role of the National Advisory Committee on Core Health and Disability Support Services and other bodies in determining the annual policy and service obligations faced by the 4 Regional Health Authorities is discussed.
